  Purpose

This study will involve up to 20 bilateral patients per surgeon. Patients will be assessed pre-operatively, and at subsequent visits (following the implantation of the intraocular lens in the second eye) at 1 week, 1 month, 3 months and 6 months post-operatively.

Primary Outcome Measures:
  • Visual Acuity [ Time Frame: pre-operative;1 week,1 month, 3 months and 6 months after 2nd eye surgery ] [ Designated as safety issue: Yes ]
    Comparison of visual acuity (measured in logMAR) prior to and following bilateral implantation of the AcrySof ReSTOR Aspheric Intraocular Lens (IOL). Visual parameters were assessed prior to and after the implantation of the second lens at 1 week, 1 month, 3 months, and 6 months. LogMAR, the unit of measure for visual acuity, is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity.


Secondary Outcome Measures:
  • Spectacle Independence [ Time Frame: pre-op;1 week,1 month,3 months and 6 months after 2nd eye surgery ] [ Designated as safety issue: Yes ]
    Spectacle independence is the percentage of patients that do not always need to wear glasses. This outcome measure is patient reported.
